Facing error for Duplicate Entries in Specification Edit

Which kind of components are you talking about?

You would probably need to add a bore selection to the heading....

I was adding "Bend" with size 300 Right Bend, but width were different, for ex. Size 300 width 150, Size 300 width 450 and so on....

It means If all selection qualifiers are same, then It gives Duplicate error?  But catalogue component references were different

What do you mean with "width" ?

Maybe radius?

In that case you need a radius selector for your bend heading

Okay, got it. Thanks for the guidance.
